ADJUSTABLE STTPPORTIFOR MUSIC-ROLLS FOR AUTGMATIC MUSICAL INSTRUMENTS.

Specification of Letters Patent.

Patented May 19, 1908.

Application filed Match 1'7, 1906. Serial No. 306,527.

To all whom it may concern:

Be it known that 1, CHARLES FREBORG, a

citizen of the United States, residing at De Kalb, in the county of Dekalb and State of 5 Illinois,-have invented new and useful Imments means of supporting the music roll.

which is adapted to support rolls of different lengths, such as are proyided for operating a greater or less portion of the manual; that is to say, from 88 notes, for which the longest rolls are adapted, to 58 notes, which is the ordinary compass of the shorter rolls.

It consists of the features of construction set out in the specification and claims and shown in the drawings for extending the supports toward each other and securing them at the several positions which correspond to 5 the different lengths of the rolls.

In the drawings :-Figure 1 is a partly sectional lan' view of the portion of an automatic ilayer concerned in this invention with the immediately adjacent parts, the cheeks being broken away and shown in section at the axes of the music-roll-supporting spindles. .Fig. 2 is an axial section on a larger scale than Fig. 1 of the centering spindle and its support. Fig. 3 is a section at the line 5 3-3 on Fig. 2. Fig; 4 is a section at the line 44 on Fig.3. Fig. 5 is a partly sectional side elevation of the driving spindle, same being shown engaged with the head of a roll, sectionbcing made axially through the bearing and the outer sleeve of said spindle, and the head of the roll being broken away and shown in axial section with its socket ongaged with the square protruding driving terminal of the spindle. Fig. 6 is a section at the line 6-6 on'Fig. 5, showing the driving-spindle engaged witha protruding flanged terminal of the roll. .ln the drawings, the supporting frame for the rollbearings and tracker is represented i0 by the checks, 1 and 2, and the connecting base, 3. I

The tracker board is shown at i.

is the take-up roll which is proyided with ''adjustable flanges, 5?, ,which may be moved when desired.

along the roll to accommodate perforated sheets of diil'erent widths. j

6 represents the left-hand end plate of the motor frame in which are the bearings for the driving spindles oi both music roll and takeup roll. From this plate, the bearing bosses project into the right-hand check, 1, the boss, 6, being thus provided for the driving s indie of the music roll. This driving spind e is made in three telescoping sleeves, 7, 8 and 9. The sleeve, 7, has rigid with it the pinion, 7, through which power is communicated to rotate the spindle. V The sleeve, 8 within the sleeve, 7, has a slot, 8, with an offset portion, 8", for engagement with a stud, 7 which pro jects inwardly from the sleeve, .7, said slot and stud cooperating to form a bayonet lock connection between the two sleeves which permits the sleeve; 8, tobc adjusted within the sleeve, 7, the length of the slot and locked at protruded position, as shown in Fig. 5. The sleeve, 8, has another slot, 8, in the outer hall of its length, and near the outer extremity it is provided with an inwardly projecting pin or stud, 8 a longitudinal furrow, 9, with which the pin, 8, engages to guide the sleeve, 9, in itslongitudinal telescoping movement and there secured within the sleeve, 9, a s )ring,- 10, hav-v ing a portion, 10 ,which protru es out through a suitably located slot, 9 for engagement with the slot, 8, of the sleeve, 8, to lock the sleeve, 9, at its most protruded position with respect to thesleeve, 8. T0 the end of the sleeve, 9, there is secured a terminal chuck, 11. This chuck has an axial aperture to receive a pintle of the roll to be driven and is slotted across the axial aperture, as seen at 11", to engage the wings, 12, of such pintle, 12. Within the axial aperture of the chuck, 11, and the corresponding axial bore of the sleeve, 9, there is provided a plunger, 13, which is forced outward by a spring, 14, lodged behind it in the sleeve, 9, and stopped against a shoulder, 9. A thumb screw, 15, set in through the side of the chuck enters a seat formed on the side of the plunger ,by cutting away the same as seen at 13, and serves as a stop to limit the protrusion of the lun- The sleeve, 9, has

ger under the action-of the spring and a so as a set screw to hold the plunger retracted The plunger has a square terminal, 13, which at the outermost position protrudes from the chuck and is adapted to ed on the lodged in a socket on phragm or plug,

and drive eith r a roll having a socket such as shown in Fig. 5, in which case the square terminal, 13 affects the driving engagement,

or a roll having a protruding driving pintle,

12, as shown in Fig. 6, in which case the engagementyis made by thewings, 12 engag ing in the slots, 11 of the chuck, the plunger being thrust back into the cavity of the sleeve, 9, and referably, though not necessarily, held thus retracted by the thumb screw, 15, operating as a set screw. For a roll of the next shorter length, as65 notes, the sleeve, 9, is drawn outward in the sleeve, 8, the latter being left at its inner position in the sleeve, 7, stopped at the bottom of the 'cavity of the latter sleeve where a diaphragm or plug, 16, is provided for that purpose, the sleeve, 9, being stopped against inward movement in the sleeve, 8, by the engagement of the bend, 10 of the spring, 10, in the slot, 8, of the sleeve, 8. For the shortest roll, 58 notes, the sleeve, 9, being left protruded from the sleeve, 8, as above described, the sleeve, 8, is drawn outward in the sleeve, 7, tothe limit of the slot, 8, and locked with the-pin, 7", by a slight rotation, as may be understood from Fig. 5. Preferably, the end thrust of the spindle is taken by a stop bracket, 17, mount' motor frame plate, 6, and projecting past the end of the spindle, and to reduce the friction of such end thrust the actualbearing is, formed by asteelball, l8, whichis the outer side of a dia- 16, and bears against a clip, 19, which is arranged to slide on to the end of the bracket, 17, as may be understood from comparison of Figs. 1 and 5.

20 is a centering spindle for the opposite end of the music roll. It is mounted for sliding through a bearing flange or bracket, 21, which is secured to the inner side ofthe left-hand cheek, 2, and is provided with a protruding boss, 21 of sufficient length to adequately guide the spindle 20, and hold it accurately alined with the driving spindle while permitting it to slide through it for the adjustments hereinafter described. Gn the back side of the bearing flange, 21, there is mounted a latch, 22, pivoted at one side of the bearing of the spindle and extending across to the opposite side, and rovided with a' spring, 23, tending to 1101 its nose or spindle engaging projection, 22*, inward toward the axis. vided withthree annular grooves, 20**, 20? and 20, at such positions and distances apart the latch, 22, it is provided projects through a slot, 21",-

. ports and a center ,the other, said driving and centering elements being adjustable with respect to their said fixed supports toward and from each sisting 7 which are adjustable relatively for protiuding the driving terminal more or less, means The spindle, 20, is proceases so provided, groove, 20, the spindle-is in proper position to accommodate the longest roll. When the latch is engaged with the groove, 20 the spindle is protruded to the positionfor engaging the roll of the next shorter length, 65 notes, and when the latch is engaged'with the groove, 20, the spindle is at proper position for engaging the shorter roll, 58 notes.

2 5 is the terminal for ing the rolls. 20,in the inner end of the spindle and thrust outward by'a spring, ing stopped by a pin, space between the two reducing the pin in diameter at 25 for a distance equal to the yielding movement atany time to be required of the terminal, 25. This terminal is adapted to engage and center, either the roll which has a socket or the roll which has a protruding pintle, the reduced end, 25, entering the socket of a socketed roll, and the pintle of a roll so pro- 26, which takes'into the vided entering the socket, 25, in the end of,

the reduced terminal, 25. For operating with a finger piece, 27, which in the flange, 21, so as to be readily accessible at the inner side of the check, 2.
